Just a reminder in this case: EU prices include the VAT (near 20% in many cases), while in the US the state tax (often 10%) is not included in public prices.
This also accounts for different prices in different European countries; e.g.: the cost of making business is very high in Italy (high salary taxes, high network costs, impossible to fire/sack people, etc.) so they make their products cost more in Italy to account for the additional costs of running operations there.
There's no Apple retail or marketing in Belgium.
